We don't have a way for you to look up oem parts yet but you can use the parts search HERE to get part numbers then use the OSD search to see if we have what you need. If the part doesn't show contact us and we'll add any parts not listed to our site (if not discontinued).
If a part shows "0" in stock...
When searching our site, you may notice out of stock parts. Parts not in big demand aren't kept on hand but we can usually get any out of stock item in quick. On our OSD parts (will have OSD in the title) and aftermarket parts we can usually have those here in 2-3 days once ordered. On most OEM parts those take about a week to get in. If you want one disregard any "0" quantities and order for quick service!

One of the most overlooked parts to a Sea Doo is the buzzer alarm. Almost every ski that comes in our shop has a non functional buzzer. That's because over time moisture kills them. It's just the nature of the beast when it comes to those. People don't realize but not only does it give you the two beeps when your lanyard is installed (on most 1996 and newer models), but it's most important function is to alert you if the engine is overheating. So basically the failure of a $50 part can cause you to seriously damage your engine if your cooling system gets plugged or a hose breaks. If you want to know if your buzzer is faulty, the test is simple... with the lanyard removed, push the start button. That engages power for about 1/2 minute and during that time, take the heads temp sensor wire and ground it to the engine. If the buzzer doesn't sound, it's most likely dead.

Now offered are our OSD buzzer assemblies that feature a "Made In USA" buzzer (the same one Sea Doo uses) and are built to the same specs (length, wire color, etc) as oem Sea Doo parts. Additionally, the terminals aren't just crimped but soldered then crimped for the best electrical conductivity and corrosion resistance you'll find. In the environments these are exposed to, you want the best so that's what we offer! The current replacement (278001586) doesn't come as a complete assy with terminals and ready to install like ours. Our buzzer assy includes a new plug that hasn't been installed yet so all you have to do is pull the wires through then install the plug and you're back in business. Just make sure to match the wire colors to the other connector when installing the plug. Replaces Sea Doo p/n 278000887 used on the models listed below.

Note that as is the case with your local dealer, there is no warranty on new or used electrical parts purchased from us. The reason is that we buy electrical parts with no warranty from our supplier so can't return one no matter what the situation. Since you're ultimately the one who wants to get back on the water, you assume all risk for purchasing a replacement part and agree you will not hold us responsible if it doesn't work or doesn't fix your particular problem. All electrical parts are thoroughly tested at the factory before being shipped to us so they should be in proper working condition when you receive one. We sell lots of electrical parts with few complaints but part failures do rarely occasionally happen so keep that in mind when considering a replacement part. Finally, you'll need to make sure all other electrical components are in proper working condition BEFORE installing a replacement part.

If you've bought one of our carb kits, a great page by GroupK that details the procedures for carb fine tuning can be found HERE

If you're installing an impeller on a Sea Doo, don't follow the manual when it calls for red loctite on the threads... use anti-sieze instead. That way if you want to take it apart again you can. We've built hundreds of pumps now with anti-seize and it works great!
